The Health Forum for DUAL ELIGIBLES

We should re-post this Free admission 2-hr Forum at UCLA on 9/19/2012.


"Covering and Caring for Dual Eligibles"

There are nearly 9 million so called "dual eligibles" -- low income seniors and younger people with disabilities -- who qualify for both Medicaid and Medicare benefits. They are among the country’s sickest and poorest populations and frequently encounter great difficulty navigating the complex and uncoordinated systems of the two beneficiary programs. The Affordable Care Act contains provisions to improve the quality of care delivered to dual eligibles while better controlling costs. The panel will discuss the implementation and challenges involved in managing care for dual eligibles.

When: Wednesday, September 19th, 6:30-8:30pm
6:30-7:00pm: Coffee and Reception
7:00-7:45pm: Panel Presentations
7:45-8:30pm: Question and Answer Session

HIPPA and PHI

Under the US Health Insurance Portability and Accountability Act (HIPAA),  protected health information (PHI) that is linked based on the following list of 18 identifiers must be removed,
(Source: http://www.ucdmc.ucdavis.edu/compliance/guidance/privacy/deident.html),


  1. Names;
  2. All geographic subdivisions smaller than a State, including street address, city, county, precinct, zip code, and their equivalent geocodes, except for the initial three digits of a zip code if, according to the current publicly available data from the Bureau of the Census:
    1. The geographic unit formed by combining all zip codes with the same three initial digits contains more than 20,000 people; and
    2. The initial three digits of a zip code for all such geographic units containing 20,000 or fewer people is changed to 000.
    3. Currently, 036, 059, 063, 102, 203, 556, 592, 790, 821, 823, 830, 831, 878, 879, 884, 890, and 893 are all recorded as "000".
  3. All elements of dates (except year) for dates directly related to an individual, including birth date, admission date, discharge date, date of death; and all ages over 89 and all elements of dates (including year) indicative of such age, except that such ages and elements may be aggregated into a single category of age 90 or older;
  4. Telephone numbers;
  5. Fax numbers;
  6. Electronic mail addresses;
  7. Social security numbers;
  8. Medical record numbers;
  9. Health plan beneficiary numbers;

Summary of UCLA Health System's HIPAA Policies

1. Protection of Health Information

UCLA Health System Workforce members may not disclose, share or otherwise use any individually identifiable health information except for treatment, payment, and health care operations (referred to as "TPO") unless expressly authorized by the patient or as otherwise permitted by law.  Patients also have the right to request that UCLA restrict how their PHI is used or disclosed.

2. Classification of PHI Information

All information contained in patient medical and billing records is confidential regardless of format.  These confidentiality protections extend not only to the patient's medical record, but also to information from the record.  In addition, special laws govern the disclosure of mental health, substance abuse, and HIV test result information. 

3. Notice of Privacy Practices

The Privacy Rule requires UCLA Health System to give each patient detailed information about UCLA Health System's privacy practices, in the form of the University's "Notice of Privacy Practices" (see "Other Forms and Documents").  All uses and disclosures of PHI by UCLA Health System and its workforce members must be consistent with the Notice of Privacy Practices.

4. Authorization to Use PHI

The Privacy Rule requires providers to obtain a written authorization from an individual before using or disclosing a patient's PHI for purposes other than for TPO, unless otherwise authorized by law.

5. Patient Access to PHI

The Privacy Rule gives an individual (or that person's personal representative) the right of access to inspect and obtain a copy of the individual's own PHI.  Providers may deny an individual access to his or her information under certain circumstances only if specified procedures are followed.
All requests for information from medical records should be referred to or coordinated with UCLA Health Information Management Services.

6. UCLA Health System Employee (Workforce) Responsibilities to Maintain Confidentiality of PHI

All members of the UCLA Health System workforce are responsible for maintaining the security and confidentiality of PHI on behalf of UCLA Health System patients. 
  • Minimum necessary: When using or disclosing PHI, a provider must make reasonable efforts to limit PHI to the minimum necessary to accomplish the intended use, disclosure, or request.
  • Employee access: All members of the UCLA Health System workforce should only read and use PHI as necessary for their job functions.

7. Release of PHI to Third Parties

In light of the specific accounting and disclosure requirements imposed by HIPAA, all copying of medical records for release to third parties or agencies must be completed by, or coordinated with, UCLA Health Information Management Services

8. Privacy Requirements Relating to Research

Research is not considered to be a part of TPO under the Privacy Rule, except for certain studies related to health care operations, such as research that is also considered quality assurance and utilization management activities.  Consequently, the use or disclosure of PHI for research purposes generally requires either: (1) a written authorization from the individual whose information is collected or (2) a waiver of authorization from UCLA's IRB. The IRB is responsible for reviewing and approving the authorization form that is used for research.
The Privacy Rule permits the use and disclosure of a limited data set of information for research purposes, without patient authorization, provided certain requirements are met, including entering into a Data Use Agreement with the recipient of the information.
Health Information that does not identify an individual ("de-identified information") is generally not considered PHI and may be disclosed without the patient's authorization.  In order to de-identify PHI, UCLA Health System must remove all 18 of the HIPAA identifiers specified in the HIPAA Privacy Rule.

9. Disclosures to Business Associates

The Privacy Rule requires UCLA Health System to enter into a confidentiality agreement with certain third parties when UCLA Health System shares PHI with the third party (e.g., non-health care providers) for TPO purposes.  This is called a business associate agreement ("BAA"). A business associate relationship exists when an individual or entity, acting on behalf of UCLA Health System, assists in the performance of a function or activity involving the use or disclosure of UCLA Health System's PHI.  The UCLA Purchasing Departmentsare responsible for completing the University's HIPAA-compliant business associate agreement with outside vendors that provide goods or services to UCLA Health System. The UCLA Health System's form BAA can be found on the UCLA Health System Office of Compliance Services website. 

10. Marketing and Fundraising

In general, PHI may not be disclosed for marketing purposes without the patient's authorization. PHI includes demographic information, without any accompanying diagnosis or treatment information.  An authorization must be obtained from the patient even to use the patient's address or phone number for marketing.
In addition, all fundraising materials sent to an individual must describe how the individual can opt out of receiving further fundraising communications.

11. Media Inquiries

Both California law and the Privacy Rule restrict the amount of information that may be provided to the media without the patient's authorization.  In general, UCLA Health System may release the condition and location of an inpatient, outpatient, or emergency patient, but only if the inquiry specifically contains the patient's name, and only if the patient has not requested that the information is withheld from disclosure.  No information can be given if a request does not include the patient's name or if the patient has requested that information be withheld.
A patient's condition may only be described in general terms that does not communicate specific medical information about the individual.  For example, the following general terms are acceptable: "undetermined," "good," "fair," "serious," "critical," or "deceased."

12. Safeguards to Protect PHI

Reasonable safeguards (physical, electronic and administrative) are to be used at all times to ensure that confidential information is not disclosed to individuals who are not authorized to receive the information and to minimize incidental disclosures of PHI.  Examples of safeguards (such as locking medical and billing records at the end of the day, not sharing passwords, etc.) can be found on the UCLA Health System Office of Compliance Services website, and in UCLA Health System policies, such as Policy HS 9401.

13. UCLA Health System Workforce Training and Education

The Privacy Rule requires that providers train their "workforce" on privacy policies and procedures at a level appropriate for the workforce members to carry out their roles and responsibilities.  All members of the UCLA Health System workforce will be provided with essential instruction regarding Privacy Rule requirements and additional training specific to their job responsibilities.

14. Unauthorized Release and Disclosure

The unauthorized release of PHI is a violation of law, with potential civil and/or criminal penalties and fines.  In addition, workforce members who are found to have violated the law and/or UCLA Health System policies may be subject to disciplinary action, up to and including termination.  Workforce members should immediately report any unauthorized release or disclosure of PHI to the Privacy and Information Security Offices and their supervisor.








Best Consulting Skills

The September issue of ASA news post the article <Consulting Best Practices>. We all believe that there are more important necessary characteristics/skills of a good statistical consultant beyond the technical expertise. The most important characteristics, suggested by practitioners and clients, are the interpersonal skills, the ability to and interest in listening carefully and fully to the client, an appreciation for the client's concerns. Below is my summary notes based on the article.

The purpose of statistical consulting can be as simple as helping understand a perceived problem or as complex as implementing a solution. All the procedures required better communicate effectively at and with all levels of an organization.  “Seek first to understand, then to be understood. Communication is the most important skill in life.” The article list the skills,


  • Professionalism
  • Time management
  • Judgment
  • Team player
  • Good communication
  • Good listening
  • Roles and responsibilities
  • Involving other consultants
  • Reputation


  • Skill in structuring task
  • Technical knowledge/skills
  • Industry experience
  • Commitment to clients
  • Getting along with clients

Suggestion: An important element of good communication between the client and consultant is defining the boundaries of the work. It’s as important that you indicate what you won’t do as it is to describe what you are committing to do. Of course, once you get into the project, you may see something that wasn’t obvious from the outset. You can always provide optional steps that would extend the range of the original agreement and that may require additional resources.In almost any consulting task, assumptions must be made, as few projects will be so obvious that no assumptions are required. It will be to your credit to clearly identify and state these assumptions and, to the extent possible, emphasize their implications. Knowing what is too much effort to expend for the next improvement step is a valuable attribute of a good statistical consultant.

Some of the tools that can help the communication could be agendas, flowcharts, checklists, and minutes from meetings. Following are several important steps in ensuring meetings are efficient:
  • Include the right people
  • Set an agenda
  • Stick to the agenda
  • Follow up the meeting with minutes
Taking and distributing minutes that summarize key points of agreement and disagreement—including action items and next steps—and identify the responsible person and a tentative due date helps move from the meeting to problem resolution.

The most efficient solution may never work if the people who need to bring it about do not benefit in some way from the change. Even more basic, many have an understandable motivation to continue using tried-and-true methods. It may be important to ensure the staff is involved in the development of the new procedure and ‘buys in’ to the new methods.

Finally, never forget that ethical issues undergird all our work. Following accepted ethical practices is a necessary requirement for any statistical consultant.


We will definitely need to learn new knowledge to break the boundaries to serve as the statistical professionals.

Oral Health Topics in NHANES 2009-2010

In this post, we discuss some results related to oral health questionnaire for the most recent national data source NHANES 2009-2010. The oral health question were asked to those sampled subjects who are 30+ years old by the trained dentists. The reference page is http://www.cdc.gov/nchs/nhanes/nhanes2009-2010/OHQ_F.htm. Data can be downloaded through: Oral Health (Data [XPT - 366 KB]) (April, 2012 last updated)

The data will represent 177,284,326 size in the population. The related oral health questions are,

OHQ835Do you think you might have gum disease?
OHQ845Rate the health of your teeth and gums
OHQ850Ever had treatment for gum disease?

OHQ860Ever been told of bone loss around teeth
OHQ865Noticed a tooth that doesn't look right
OHQ870How many days use dental floss/device
OHQ875Days used mouthwash for dental problem

SEQN exists for every data set. This is the unique ID for every subject. When using the data to represent the  National Statistics, we need the following variables from the demographic data,
WTINT2YRFull Sample 2 Year Interview Weight
WTMEC2YRFull Sample 2 Year MEC Exam Weight
SDMVPSUMasked Variance Pseudo-PSU
SDMVSTRAMasked Variance Pseudo-Stratum
 The difference between the two weights is whether you will use the MEC exam data. If you need to use that data, the weight should be WTMEC2YR because of the additional missing values in the MEC exam data. If only use the interview questions, we need to use the following macro,


%macro wtfreq(indata,var);
